Combustion chamber wall of a gas turbine with a fixture of a combustion chamber shingle

Abstract

The invention relates to a combustion chamber shingle of a gas turbine combustion chamber with at least one securing bolt that is configured in one piece with the combustion chamber shingle, characterized in that the securing bolt is provided in one piece with a bolt disc that is arranged at a distance from the combustion chamber shingle, and that a free end area of the securing bolt is provided with a thread, as well as a combustion chamber wall for attaching the combustion chamber shingle by means of a nut.

1 . Combustion chamber shingle of a gas turbine combustion chamber with at least one securing bolt, which is configured in one piece with the combustion chamber shingle, wherein the securing bolt is provided in one piece with a bolt disc that is arranged at a distance from the combustion chamber shingle and wherein a free end area of the securing bolt is provided with a thread. 
     
     
         2 . Combustion chamber shingle according to  claim 1 , wherein the free end area of the securing bolt that is provided with a thread has a larger diameter than the area of the securing bolt between the combustion chamber shingle and the bolt disc. 
     
     
         3 . Combustion chamber shingle according to  claim 1 , wherein the bolt disc has a conical shape in cross-section. 
     
     
         4 . Combustion chamber shingle according to  claim 1 , wherein the bolt disc is configured in a dish-shaped manner as a biasing spring. 
     
     
         5 . Combustion chamber shingle according to  claim 1 , wherein the bolt disc has a larger thickness radially inside than at the radially outer area. 
     
     
         6 . Combustion chamber wall of a gas turbine combustion chamber with a combustion chamber wall and at least one combustion chamber shingle that is mounted at the inner side of the combustion chamber wall according to  claim 1 , wherein the bolt disc abuts the combustion chamber wall, and the securing bolt is screwed in at the combustion chamber wall by means of a nut. 
     
     
         7 . Combustion chamber wall according to  claim 6 , wherein a washer is arranged between the nut and the combustion chamber wall. 
     
     
         8 . Combustion chamber wall according to  claim 6 , wherein the bolt disc and/or the washers is provided with at least one cooling air recess. 
     
     
         9 . Combustion chamber wall according to  claim 6 , wherein the washer is provided with a ring flange, which surrounds the securing bolt and extends through a recess of the combustion chamber wall, through which the securing bolt is guided. 
     
     
         10 . Combustion chamber wall according to  claim 6 , wherein the external diameter of the bolt disc is substantially equal to the external diameter of the washers. 
     
     
         11 . Combustion chamber wall according to  claim 6 , wherein the load path for attaching the combustion chamber shingle at the combustion chamber wall extends through the securing bolt, the bolt disc, the combustion chamber wall, the washers, and the nut.
